Abstract: A blind system may control (e.g., automatically control) an amount of daylight entering a window on a façade of a building to prevent direct sunlight from shining into the building, while maximizing the amount of indirect sunlight in the building. The blind system may tilt one or more slats into a view tilt position in which the slats are horizontal, a slanted tilt position in which the slats may block direct sunlight from shining into the building, and a privacy tilt position in which the slats are vertical. The drive unit may tilt the slats according to a timeclock having the event times determined from a predicted position of the sun, such that the slats are tilted to the slanted tilt position when the predicted position of the sun indicates that direct sunlight is incident on the façade. A facing direction of the façade may be configured using a mobile device.
